Resetting Lady

I got into a novel.
If I can find my true love, I will have a happy ending
But when it came to the end, I accepted death. After opening my eyes again, I was back to the starting point.
I fell in love once more. But in the end, death still greeted me.
Poisoned, suffocated, died from a fall, crushed, starved,…
On my 117th birthday, Karen Hier – I decided to be a killer.
